Astronomers have been puzzled and annoyed about the extensive media publicity that was given the small group of true believers who claimed the Face on Mars was not a natural formation (see the Astronomy and Pseudoscience: The Face on Mars feature box in Section 10.5). The biggest difference between the two is their distance from the sun: Venus is closer to the sun than Earth so it has a much hotter surface temperature and atmosphere. Only the inner planets in the Solar system have solid surfaces (Mercury, Venus, Earth, and Mars). Additionally, it lacks many impact craters alluding to surface is comparatively youthful, about 300-600 million years of age.

Then we began to find planets around other stars and we learned that our solar system is if not an oddity by no means typical. The surface pressure on Mars is almost zero. Through Project Magellan, the top of Venus was mapped and located to exhibit proof of volcanism. The closest approach distance between Mars and Earth is about 56 million km. As a matter of fact, all the rocky planets of the Solar system (Mercury, Venus, Earth, and Mars) have many similarities. Near the martian equator, temperatures at the same spot can vary from an average of 135 C at night to an average of 30 C during the day. Compare the current atmospheres of Earth, Venus, and Mars in terms of composition, thickness (and pressure at the surface), and the greenhouse effect. Both planets have winds.
